Title: Exhaust particulate removing device of diesel engine
Inventor: HAYASHI KOTARO
IPC: F02B3/06
Filed: 1993-03-26
Abstract: PURPOSE:To properly control an EGR(exhaust gas recirculation) for reducing the formation of NOx by controllably correcting the EGR amount according to an amount of secondary air returned to an intake path in the regeneration of a particulate collecting filter. CONSTITUTION:When an amount of particulates collected in filters 5A, 5B exceeds a predetermined value and a differential pressure value detected by a differential pressure sensor 10 between the upstream and downstream of filters 5A, 5B exceeds a reference value, the regenerative process for the filters are practiced. Then, an exhaust particulate removing device 21 closes an intake controlling valve V0 in the regeneration of the filters 5A, 5B to generate negative pressure in an intake path 1A. While secondary air supplied to the filters 5A, 5B by such negative pressure is introduced from an atmospheric opening end of a regenerating gas feed pipe 7, an actual amount Ga of intake is reduced by filter regenerating combustion gas introduced in the intake path 1A to accordingly correct and EGR amount. As a result, the amount of EGR is properly held even if the filters 5A, 5B are practically regenerated.

Filed: 1987-03-25
Abstract: PURPOSE:To store a system control program and data proper to a system separate from each other in a simple constitution, by reading the data proper to the system into a microcomputer system and transmitting the necessary data to another microcomputer system. CONSTITUTION:When a system A is started, a RAM 5, an I/O 6 and a serial I/O 3 are first initialized. Then data are read out of a serial ROM 4 and it is judged whether these data belong to a system B or not. If so, the data are transferred to the system B via the I/O 4. If not, the data are stored in the RAM 5. The reading operation of the ROM 4 is repeated if the data stored in the ROM 4 still exist. When the data are thoroughly read out of the ROM 4, the system A is controlled with reference to the data stored in the RAM 5. In such a way, the system data can be changed by substituting and changing the ROM 4 only in a simple constitution and the simple control.

Filed: 1979-06-04
Abstract: PURPOSE: To make it possile to eliminate the need for the adjustment of an input part by alternating an analog input signal with an analog reference signal by a multiplexer, by converting its output into a frequency signal and by correcting an input signal value by a reference signal value.  
     CONSTITUTION: Analog input signals e 1 We n , and analog reference signal sources eSF and eSZ are input to multiplexer MX10. Then, MX10 outputs input signals and reference signal sources alternately and its output voltage is converted into frequency signal 3 by voltage frequency V/F converter 2. Signal 2 is counted by counter 4 as long as certain time T preset by timer 7 and its count value is converted into digital signal 5, which is input to digital processor 6. Processor 6 corrects digitally a digital signal, equivalent to the input signal, by a ditital signal equivalent to reference signal source eSF or eSZ. Consequently, even if the fluctuations of the conversion gain and count time of V/F converter 2 and a bias error happen, no influence is exerted and the need for the adjustment of the input part is eliminated.

Title: Extermination of mites in carpet
Inventor: OKUNO MASAHARU
IPC: A01M29/14
Filed: 1991-03-08
Abstract: PURPOSE:To enable exterminating sites in a carpet without leaving their carcasses therein in a simple manner by a method wherein a heating means produces temperatures in a gradient in the carpet and the sites inhabiting it pre driven away toward the lower-temperature side alive and removed at a specified spot. CONSTITUTION:First a carpet 1 is folded in two. After fitting it at one end with a troughlike device, a site extermination-operating switch is turned on. Then a rotary switch RS rotates, applying current to heater elements R1, R2,... in turn so that the heated zone gradually shifts from one end of the carpet 1 to the other. The operating time is about 30 minutes in terms of a carpet sized two jo (approximately two meters square) and the temperature of the heated zone, particularly at the main body part of the carpet, is raised to about 50 deg.C, i.e., about the highest point in the ordinary use. A high temperature effective for destroying mites is not used for the reason that the sites left unremoved after a single cycle of heating are certainly driven away to the end and eventually removed through heating repeated a number of times.

Title: Crucible for high-frequency melting of gold metal
Inventor: KUTSUKAKE TOKUJI
IPC: F27B14/10
Filed: 1988-03-23
Abstract: PURPOSE:To ensure that thermal strain induced in a crucible is so slight that the crucible is not broken by the strain and prevent a molten gold from leaking out, by disposing an inner cylinder crucible of alumina and an outer cylinder of alumina concentrically with a predetermined gap therebetween, filling the gap with an alumina powder, and uniting the three members in a body. CONSTITUTION:An alumina crucible 1 is disposed concentrically in an outer cylinder 2 of alumina, with a gap of 3mm between the crucible 1 and the bottom surface of the outer cylinder 2 and between the crucible 1 and the inner peripheral surface of the cylinder 2. The gap is filled with an alumina powder 3 having a particle diameter of 0.1-0.5mm, and the three members are united in a body. This crucible 4 was placed in a high-frequency induction heating furnace 5, and was filled with gold metal particles 6 having a size of 2-2.5mm in an amount of 70% based on the internal volume of the crucible 4. When the furnace 5 was operated to start melting of the gold metal particles 6, the particles 6 could be melted satisfactorily even under a low magnetic field inducted by high-frequency waves, because of the great heat-insulating effect of the three-wall construction of the crucible 4, so that flying of the particles 6 did not occur. In the crucible 4 for high-frequency melting of the gold metal, the temperature difference between the inside and the outside of the inner cylinder crucible 1 is small, so that the crucible 1 will not be broken by thermal strain.

Abstract: PURPOSE: To provide a dry toner contg. an electric charge controlling agent made of an azo dye mixture by incorporating resin particles, a coloring material and an electric charge controlling agent contg. 'Zapon Yellow 141(R)' made by BASF Corp. CONSTITUTION: This dry toner contains resin particles, a coloring material and an electric charge controlling agent contg. Zapon Yellow 141 consisting of about 95wt.% Solvent Yellow 81 and about 5wt.% Solvent Orange 56. The pref. amt. of the Zapon Yellow 141 is 0.25-0.75wt.% of the total amt. of this toner. The resin particles are preferably based on a styrene-acrylic copolymer. This dry toner is used in combination with an uncoated ferrite carrier. A large amt. of Zapon Yellow 141 increases the quantity of electric charges in a short period of time but its transfer to the carrier reduces the ability of the carrier to electrostatic charge the toner.
